Installing an accurate aftermarket tachometer on diesel applications has been problematic, until now. AutoMeter diesel tach adapters are ideal for all vehicles equipped with an alternator needing an accurate tach signal. A small pick-up probe is strapped to the outside of the vehicle's alternator and inductively leads its rotation, thus requiring no drilling or modifications for installation.

With simple one-touch calibration and widespread uses, AutoMeter diesel tach adapters are just what you need.
